3DMark
We used 3DMark‘s ‘Fire Strike’ benchmark which is designed to be used on gaming PCs. We opted for the Normal setting, NOT the Extreme mode.
Sandra Processor Arithmetic
Sandra Memory Bandwidth
Gigabyte's X99M-Gaming 5 has no problem keeping pace with full-sized ATX competitors in the 3DMark and Sandra benchmarks.
Memory bandwidth on Gigabyte's mATX part is slightly higher than that of the competition's. That could be related to shorter path distance between the board's four DIMM slots and an LGA 2011-3 CPU.
